MAGNETO-ELECTRIC POCKET LAMP.

Application filed August 26, 1924. Serial No. 734,297.

rIhis invention has for its object a magneto-electric pocket lampprovided with a tubular protectingcasing within which is securelymounted an inducting magnet adapted to be actuated by a driving gear andhaving iixed therein an inductor, the features oi' novelty in thisapparatus consisting therein, that one of the axles or shafts axiallyarranged to and connected with either end of the inductor serving forthe production of the electric current is securely mounted in the closedend oit the `tubular casing, while on the opposite end of the inductorthe second centre axle or shaft is bolted to a casing containing thedriving gear. In this way a connection between the inductor and theelectric lamp is effected by means of a contact pin, the latter' beingiixed in an insulating sleeve mounted in the. second of the aforesaidaxial shafts and, with one end of the anchor winding, being guidedthrough a bore provided in the last named shaft. Simultaneously withthis operation an insulating contact device arranged in the driving gearcasing is caused to make connection with the electric lamp of the innerelectric circuit, while the outer circuit is led over the protectingcasing. Further novel features consist in that the driving gear casing,which comprises several parts, is held together by means of twoscrew-bolts, ot which one is at the same time clamping a spring havingthe tendency to raise the bar of a rack from the driving gear casing andmake it engage with a pinion of the driving gear. The latter possesses acouplingcomprising two coupling-wheels of which one is spring-controlledand made to engage with the other when the apparatus is actuated. One ofthe coupling-wheels is furthermore meshing with a gear wheel which bymeans of intermediate gear'wheels transmits its movement to a toothedwheel mounted with its flanged part in a flange attached to the magnet.Owing to the screwing together of the several parts of the casingcontaining the driving gear by the aid ot the screw-bolts the said gearis guided by and bearing in the casing and prevented from displacementin an axial direction.

Referring to these drawings, l designates av tubular protecting casingot which one end is closed while into the other end, the socalledlamp-head 2, the electric lamp 3 is screwed. 4t is a check lever bymeans of which toothed bar 34 adapted to actuate the driving gear isstopped trom movement when the apparatus is not used. For themanipulation of the bar 534i a knob 5 is screwed into the same. n p

Y The closed end oi the protecting casing l is of a suitable thicknessand strengthiin order to receive and securely hold in a cylindricalrecess therein an inductor shaft 6 of which one end extends through abore in the head part ot a magnet l5 which, longitudinally, is ofU-shaped section, the other end :iii

of the shaft 6 carrying a disk 12. There is also a central axiallydisposed shaft 7 mounted at the other end ot' the inductor, this shaftcarrying a disk 8 and being hollow and at the right hand end providedwith screw-threads,Fig. 3. Leading throughthe hollow shaft 7 is anelectric conductor which is disposed within an insulating sleeve 9 andconnected with a contact pin 10, saidj conductor also extending throughanother insulating sleeve 46 fitting into the bore of the sha'tt 7. Thedisks 12 and 3 are in connection with the'inductorll which seen in crosssection has double T-Orm, Fig. 5. TWound around the iron core 11 is thewiring 13 which with the core `forms the inductor.

The U-shaped magnet is rotatably mounted upon the inductor and, by meansof a sleeve 13 secured on the shaft 6, journaled thereon. Attached tothe open end of the magnet, that is, to the ends of thetwo parallelmembers of the same, by screws 17, is a guiding flange 16, in such amanner, that the magnet 15 with the said flange is also rotatable on theshat't 7. Between the outer end of the inducting magnet 15l and theprotecting casing 1 a small space for play is provided. The guidingiange 16 is formed with a nave which carries a toothed wheel 19 adaptedlto rotate on the shaft 7.

The inductor is connected by bolts with a casing containing the drivinggear and con-- sis'ting of the tour parts 20, 21, 22, and 23, Figs. 2and 3, which are secured to each other and to the protecting casing 1 bythe screw-bolts 33 and 37. Ot these parts that denoted by 21 contains aninsulating sleeve 24 in the one recess of which a` set-screw 25 isarranged and made to securely hold a rightangle shaped contact plate 26.The screw 25 engages with, that is, it is screwed into a nut situatedwithin a second recess in the sleeve 24, which nut 27, by means ofaspring 28 is in electrical connection with the contact pin 10. Thecontact plate 26 is connected with a contact blade 3() fixed upon andextending into the insulating disk 23, Fig; 4, and thus forms theelectrical connection from the inductor 11 to the electric lamp 3. TheContact blade 30 is hereby held fast on the insulating disk 23 by aset-screw 31. One pole of the winding 13 is therefore connected with theone contact of the electric lamp by the members 25, 26, 27 and 30,whereas the other pole of the winding, for instance for an insulatingprotecting casing, is in electrical connection with the other contact ofthe electric lamp by means of the parts 11, 3, 7, 21 and the bolt 33,which also secures a contact blade 32 on the insulating disk 23.

The holding fast in position ot the toothed bar 34, as alreadymentioned, is eected by means ot the checking lever 4 which is pivotallymounted" in the casing 1 and provided position shown in Fig. 14 intothat illustrated. in Fig. 15, Eni the position shown in Figs. 13 and 14the bar 14 is stopped from movenient in the casing. By swinging thechecking lever about an angle of 13()O the toothed bar is rendered tree,owing to the recess 4T Abeing brought into the sliding plancof the Thedriving movement takes place in the ollowing nia-nner. T'lieiniddleportion ot van axle or shaft 14, which forms an integral part with theYtoothed wheel 40, is ot square Isection and arries an axially slidablycoupling wheel 42 kept in engagement withv the wheel 41 by the spring43, the wheel 41 being freely and* rotatably mounted upon the right-handcylindrical portion ot' the shaft 14. The toothed wheel 41 engages witha gear wheel 39, Fig. 11V, which is rigidly connected' with another gearwheel 38, the latter rotating the toothed wheel 19 and with it themagnet. rlhe toothed bar 34, which is capable of upward and dowi'iwardmovement, engages with thev toothed wheel 40. Upon the projecting end ofthe said bar a handle 5 is screwed.

W'hen the toot-hed: wheel 40 is turned during the downward' movement ol'the bar 34, the coupling' wheel 42 will' cause the rotation ofthe wheel"41. lt, however, the wheel 42 vis rotated in the opposite direction,which i's thecase when the toothed bar is moved upwards, the wheel 42only, rotates, because the bevelled faces of the teeth of the wheels 41and 42 slide away over each other so tha t the magnet is in no wayhindered in its rotation. Part of the coupling wheel is formed as gearwheel. The pinion 39 is cary ried by a sleeve 44 lined in the disk 2land is connected with the gear wheel 33. Both whe-els 33 and 39' arejournaled in and guided by the disk 20. y

rl`he toothed bar 34, which has lined to it a pin extends through a slotprovided in the disk 22, is under the control of a spring1 36, Fig. 9,which preferably consists of two or three thin steel blades mounted oneupon the other. One end ot this spring is secured to the pin of thetoothed bar and the other end' to one ot the screw-bolts 33, withtheeii'ect that the toothed bar has the tendency to move upwardly.

When used the apparatus works as tollows: Assuming the toothed bar 34 tobe moved downwardly by the handle 5, the toothed wheel is made to rotateand,

through the medium of the aforementioned gear wheels a rotation of theinducting magnet caused, so that inducting `electric currents areproduced which bring about the lighting of the lamp. The spring 36 thencauses the toothed bar at once to move upwards again into the formerposition whereupon the bar is pressed down once more byhand in order toimpart a new impulse to the rotary movement of the magnet l5. Theactuation of the toothed bar is continued as long as the supply of lightis desired.
